Specification of Letters Patent.

Patented Dec. 16, 1919.

Application filed July 30, 1918. Serial No. 247,433.

To all whom it may concern:

Be it known that 1, JOHN F. BERNIK, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented new and useful Improvements in Tables, ofwhich the following is a specification.

The object'of the invention is to provide a table structure capable ofyielding vertically and laterally to compensate for jars or shocks whilecapable of maintaining a substantially stable equilibrium, and to thisend the same consists in a construction, combination and arrangement ofparts hereinafter set forth, it being understood that changes in form,proportion and details may be resorted to within the scope of the claimwithout departing from the spirit of the invention.

In the drawing Figure 1 is a side view of a table constructed inaccordance with the invention.

Fig. 2 is a sectional view of the upper or platform portion of the same.

Fig. 3 is an inverted plan view of a portion of the platform to show theattached securing plate.

Fig. 41 is a detail view showing the means for securing the supportingspring to the base ring.

Fig. 5 is a bottom plan view of the disk which is attached to the tableplatform.

The table embodying the invention consists essentially of a base 10preferably in the form of a ring which is adapted to be secured as at 11by screws or otherwise to the floor, and seated thereon is a spiralspring 12 of a suflicient gage to support the table platform 13 with theload for which it is designed. As shown, the spring which is broad atits base, is tapered upwardly to its point of attachment to theplatform, the means whereby the lower coil of the same is secured to thebase ring consisting of staples 14 or the equivalent thereof. Similarfastening means 15 are employed to attach the upper coil of the springto a disk 16 which in turn is secured to a fastening plate 17permanently attached to the under surface of the platform by means ofscrews, nails or the equivalent thereof, as shown at 18. The disk 16 issecured to the plate 17 by means of screws 19, and said disk is providedwith a sleeve 20 which extends upwardly into an opening 21 in the plate17 and is interiorly threaded for the reception of a threaded tongue 22on a counter weight 23 which depends within the coils of the spiralspring and serves as. a means for steadying the table and maintaining itin its proper supporting position.

It will be understood that while a table constructed as described willyield to slight jars, and" shocks, the vibrations for example of thefloor will be absorbed by spring support, and at the same time thelikelihood of injury as by breaking of the table top or platform fromits supports or pedestal as by applying an unusual weight to one sidethereof will be reduced to the minimum.

What is claimed is A table having a base, a spiral spring having itsbottom coil attached to said base, a disk secured to the uppermost coilof said spring, a table top or platform secured to the disk, the latterbeing provided with a central threaded socket engaging the top orplatform, and a counterbalanc ing weight having a tongue threaded intosaid socket.

In testimony whereof I aliix my signature.

JOHN F. BERNIK.
